2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

Chiropractors see many patients that suffer from a specific back problem caused by carrying the infant car seat. Right now there is nothing that can help these patients unless they place the infant car seat on a stroller made for a car seat. The stroller is bulky so most people tend not to use them for quick errands. This invention will solve this problem and help people who suffer with back injuries or prevent others who will suffer from back injuries due to carrying the infant car seat with the infant in it adding weight to the seat. This application created a new type of infant car seat. Several products and patents have been developed with infant, baby or child seats that convert into child products. Exemplary examples of patents covering these child seat products are disclosed herein.

U.S. Pat. No. 6,976,685 issued Dec. 20, 2005 to William L. King et al discloses a Wheeled Car Seat. In this wheeled car seat the wheel exist in a folding compartment located under the seat area. The handle that extends from the center of the seating acts as a front restrain. This patent does not have a base or add-on companion stroller and swing. It further does not use roller ball wheels for turning on sharp corners.

U.S. Pat. No. 6,988,736 issued Jan. 24, 2006 to Ho-Young Lee discloses a Multi-Functional Infant-Carrying Device. The handle and wheels must be connected to the car seat to create the stroller function. This patent is significantly different from the pending application because it is basically a sling with a back seat.

U.S. Pat. No. 6,986,518 issued Jan. 17, 2006 issued to Gary Lee Besaw discloses a combined Baby Car Seat and Stroller. In this patent the baby seat is essentially a stroller and the seat/stroller is secured into a base unit that mounts into a car. This patent does not combine the infant car seat and stroller as one piece with a base. The pieces are completely separate components.

U.S. Pat. No. 7,040,694 issued May 9, 2006 to Mark Sedlack discloses an Infant Car Seat and Stroller System. U.S. Pat. No. 6,695,400 issued Feb. 24, 2004 to Mitsuru Washizuku et al., discloses a Child Car Seat and Baby Carriage. These patents include a number of components that must be added or attached to the car seat to perform the functions of a stroller and elevated chair/seat.

U.S. Pat. No. 6,916,066 issued Jul. 12, 2005 and U.S. Pat. No. 6,979,057 issued Dec. 27, 2005, both to Mark Sedlack disclose an Infant Car Seat and Safety Belt System and a Mechanism for Connecting Infant Car Seat and Base. These patents do not apply closely to the patent being proposed because it is just the infant car seat with a safety belt system. This patent is just the mechanism for connecting the infant car seat to the base. The pending application uses a completely different mechanism which involves the fitting of the rollers and wheels into the base to lock it in place when the seat is used as a stroller.

What is needed is an infant car seat with a base, which when disconnected from the base the handle can be telescoped out to convert the car seat into a stroller. The proposed convertible infant stroller includes a roller ball that is placed on each side of the housing. The roller allows the car seat to make sharp turns which is a problem with most strollers and other children's carts.

BRIEF SUMMARY OF THE INVENTION

It is an object of the infant car seat to provide an easier movement of the infant car seat from an automobile to a stroller. The proposed convertible infant seat has two wheels and two rollers so that the infant in the car seat does not have to be carried when the infant seat is being moved from a car to and from a house, daycare or business.

It is an object of the infant car seat to provide ease of movement around sharp corners by using two sets of wheels and two rollers instead of four wheels. The plurality of six wheels allows the stroller to pivot forward and back from the two rollers to either of the two sets of wheels.

It is an object of the infant car seat to provide for safer movement by the person carrying the infant preventing injury to their back. Injury to the back is reduced because the parent or care giver does not need to carry the child off one side as they transport and move the child or infant.

It is an object of the infant car seat to provide safety to the infant by having a sun shade to protect the infant from the sun and from any falling objects. The sun shade protects the child from UV radiation that can sun burn the sensitive skin of an infant. The sun shade also reduces the amount of light that shines into the infant seat to make it easier for an infant to sleep.

It is another object of the of the infant car seat to provide ease of movement by being able to move the telescopic handle both towards the car seat and away from the car seat allowing a person to pull or push the car seat.

It is another object of the infant car seat to provide for the safe pivot and swivel of the infant seat through the placement of the wheels for stability. The outboard swivel roller wheels allow the infant car seat to spin around on itself to make the car seat easy to maneuver.

It is still another object of the base of the infant car seat to allow for safe transportation of the infant inside the automobile. Rather than transporting an array of equipment including a baby seat, stroller, swing and diaper bag. The convertible infant stroller provides a convertible solution with minimal separate pieces.

It is still another object of the companion add-on stroller to provide for a larger stroller with increased storage capacity for longer trips. The need to provide more storage and a larger stroller becomes more important as a baby grows into an infant, toddler and then into a young child. As the child transitions through each stage of development the amount of child clothing, food and supplies change.

It is still another object of the companion add-on companion swing to swivel to and allows the swing to go either side to side or forwards and backwards. Each child may respond differently to the stimulus of being swung side to side or front to back. The ability to change movement stimulation gives a parent or caregiver the option to clam a child with a variety of movements.

Various objects, features, aspects, and advantages of the present convertible infant car seat will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.
